In the track AK47 by W&W there's a looping effect on the word "acid" where the start and end time of the loop is initially very short and gradually increases so it goes like" a-a-a-a-a-a-a-a-a-c-a-c-a-c-a-c-i-a-c-i-a-c-i-d"

How can you replicate this effect in FL Studio. I know you can do it on direct wave, but I'm sure there are better ways

manually chopping up audio to get this would be a bitch.. I remember seeing somebody do this in edison on youtube but I can't remember the vid name

Really? I don't think it'd be that much of a pain...you could do it in a separate project file and bounce the finished project. Once you get all your parts cut right, all you have to do is copy and paste them...that'd probably give you the most direct control over the audio.

Idk about fl studio, but this is really a tracker type effect. Basically, you just set the song rate really high and use sample commands to make it so small sections loop. Here's it being done in renoise:
